T-Mobile CEO John Legere gets laughs for his raunchy talk in public, but others are taking his announcement of simplified pricing with "Un-carrier for Business" seriously.

Legere said Wednesday that T-Mobile's new pricing will cost businesses 42% less than using either Verizon Wireless or AT&T.

T-Mobile is also moving aggressively to expand its 4G LTE network to 300 million people by the end of 2015 while the company's profits are increasing more than those of competitors, "and that's what scares the hell out of them," Legere said.
